Hello everybody.

I need to build user controls dinamically into aspx page.

Besides of this, i need to put into each userscontrol different controls,
add to every control its control validators and its events.

If someone has some idea, i will say Thanks a lot.

You can dynamically "build" a custom server control. That is, you can create
a custom control which dynamically decides which controls it will contain.

It won't be a .ascx file, though.

Leon,

The answer is Page.LoadControl ... but keep reading ..

This is a classic problem even framework 2.0 fails to solve appropriately.

user controls are a combination of ascx and a code behind file in framework
1.1 and a partial class and code beside class in framework 2.0. The way they
work is, in 1.1 inherited code and in 2.0 combined code is compiled at
runtime and an Activator.CreateInstance is called on the URL location of the
ascx, similar to a webservice call .. it is like a server activated object.

So while the ascx interface is fun to play with and intuitive, (etc. etc.),
you cannot do a "new" on a usercontrol. ....

HOWEVER .. you can do a Page.LoadControl which comes darned close.

The only thing you cannot do is put UserControls along with ascx's in a dll
and distribute that as a product. That is not possible to do
